She may be the host of Rock of Love Charm School, but apparently Sharon Osbourne could use a refresher course herself.
E! News has confirmed that a police investigation has been launched after Osbourne allegedly attacked a contestant on the VH1 show, scratching her face and pulling her hair during a reunion taping on Saturday.
"We know a battery incident is alleged to have occurred on a taping of a reality show Sharon Osbourne hosts," said Los Angeles police spokesman Ben Llewellyn.
Llewellyn would not confirm whether a police report had been filed.
Megan Hauserman, 26, purportedly drew Osbourne's ire after commenting on camera that she was only famous for managing her husband, whom Hauserman dubbed a "a brain-dead rock star."
Back for the reunion special, Hauserman, who is a regular reality contestant and previous winner on Beauty and the Geek, was booted from Charm School after four episodes for kicking a fellow contestant.
Ironically, Osbourne's final words before expelling Hauserman may come back to haunt the host: "The one thing I cannot stand is violence."
